What are the Balkans?

June 28 1914 - a young Bosnian on a street corner in Sarajevo fired a shot that triggered World War One. Why is this region so unstable, and what lessons can we learn from that event. Misha Glenny was a famous reporter during the wars of the 1990s, well-placed to find answers in a region he's travelled for years. Is the violence the fault of the people who live here, or are there bigger, outside forces at work?
